ROLLER-SUPPORTING DEVICE.

To @ZZ/whom it mayconoern.' 1

Be it known that I, PAUL RnrNnnenn, a Croatian subject offthe last King of Hungary, residing at 2538 E. 38rd St., in the city of Cleveland, county ofv Cuyahoga, and State of Ohio, have invented a-new and useful Improvement in Roller-Supporting De vices, of which the following is a specification, the principle ofthe invention being herein explained and the best mode in which I have contemplated applying thatprinciple, so as to distinguish Vit `from other inventions. .Y f p MyA invention pertains to a roller supporting device and more particularly to a duplex roller bearingy construction adapted for use, as exemplified in the drawings, in

vehicles. f

One object of my invention is the provi-v sion of a roller bearing device comprising a vertically disposedV roller race adapted to be employed by way of substitution for vehicle wheels. A further object is to combine with the vertical race a superposed horizontal race in conjunction with a pivoted connection between different parts of the vehicle.

A device embodying my invention is calculated to support an immense load in proportion to its size and Ato make upward travel easier than by the employmentof al wheel, owing in part to the antifriction elements and in part to the small diameter `of the roller units. v

Adverting to the drawings T Figure I is a side elevation of a vehicle embodying my invention. Y Y Y II is a top plan view ofthe same.

Fig. III is a bottom plan view.

Fig. IV is a vertical cross IV-IV of Fig. I. y

Fig. V is a vertical longitudinal section on line V-V of Fig. IV.

Fig. form of one feature of my 'invention to be used as a turn table and showing a boX supported thereon.

Fig. VII is a top plan view of Fig. VI.

Fig. VIII is an enlarged plan view of the turn table unit. p

Fiv. IX is a section on line IX-IX of Fig. yin. Y f

Figs. I, IIv and III illustrate my invention associated with a small truck such as is commonly employed by conveying heavy merchandise from one part of a yfactory to another. Inasmuch as the construction of section' on line Y VI is a side elevation of a modified l Specification of Letters Patent. v Patented Oct. 19, 1920.

the front and rear of the truck is the same in principle only one needbe described and accordingly the singularl number Vhereinafter employed. A table 1 is secured to an annular member 2 by means of lfour cap screws l3. n The member 2 constitutes one complemental ,half of a roller race having a pair .of concentric semi-sphericalgrooves located opposite-a similar pair of annular grooves in another member 4. A plurality of balls 5 are'disposed in the grooves so as to effect a horizontal ball bearing yconnection between the members 2'and 4 when. held in place by a bolt which passes through the parts 1j, 2 and 4 as clearly shown in'Fig.` IV. Secured to theunder side'` of the member 4 on opposite sides of the longitudinal middle line are a pair of blocks 7, each block being. secured by a triple rollv of" cap screws 8. Inasmuchas the construction of thefour blocks 17 is the sameonly one will bef def f scribed.` `The block 7 Vis formed with averticallyl disposed longitudinally extendingball race 9 simulating an ellipse in a section as appears in Fig. V and the top and bottom flanged. inlet insertion opening 12 adapted to be closed byV a plug 13V in screw threaded connection with a flange 12. As appears in Fig. V, the inner end of the plug constitutes a complemental part of the wall `ofthe race 9.'l A removal of the plug 13y enables the insertion of balls`14, seven of which are shown disposed around the partition 10 and two of which are adapted simultaneously` to project sufiiciently far through the opening 11 lto simultaneously `sustain the load as appearsin Fig. V.

5A vertical bearing bracket 15 is secured to lthe forward end of the table 1 Vby means of a bolty 16 and passed through thebearingl is a shaftl 17 carrying at its top a steering wheel 18. The bottom of the shaft 17 carries a pinion 19 in meshV with a gear 20 which is fixed around'the member 4 and in turn meshes with a pinion 21 mounted upon a short shaft V22 which depends from the table 1 in between the front and rear duplicate units. The `pinion 21 engages asimilar pinion 23 on asimilarly supported shaft 24 and such `pinion 23 is adapted to turn a gear 25 similarly monnted'upon the member 4 at the rear of the vehicle. It will thus be ap-` parent that a very short turning radius is madeV possible and with a minimumof fric- Vtional resistance.

rIt is to be understood that a truck such as is shown in-Fig. I is intended to serve as a trailer Aand to be drawn behind an electric or otherwise propelled inotor vehicle.

During the movement of the trailer truck the balls 14 are moved around the partition j 10 passing downwardly infront then rolling rearwardly along the traction surface and i against the under side of the partition l0 and thereafterbeing shoved upwardly at the rear. In the meantime an operator may steer they trailer by manipulation of the wheel 18. 1

The modiication'shown on Sheetr3,Figs. VIto IX inclusive illustrates an adaptation of the horizontal roller lrace principle for` the purpose of turn table by means of which Vthe heavy articles, crates or boxes ofpmen diicing the weight of the construction. The

balls 32 are disposed around each of the-ballV races formed by the juxtapositioning of the grooves 28 and 30. The upper member 29 is provided with a central depression 33 and the lower member 27"with screwthreaded opening 34 to enablerthe Vflush insertion of a connecting screw 35.' Figs; VIv and VII show a box 36 resti-ng upon the upper member 29;

, l. A device oli-the character described, comprising the combination 'of a vehicle body, ahollow structure pivotally connected with the bottom of said bodv, said structure .being formed with a verticallyv disposed Y roller `race having its under side open, and

being also formed ,with a single-continuous substantially horizontal partition extending between opposite sides of said race, balls movable around in said race and adapted to project a limited distance through said open side so as to sustain the load of said vehicle, said structure `also including an opening to enable the insertion of said balls, and means for closing said opening.

2. A device of the character described comprising the combination of a block formed with a single integral partition and a vertically disposed roller race therearound havingY its under side open, ballsinovable around in said racc and" adaptedto Vproject a limited' distance. through said vopen side and.
